Unsolved How to partially change color of each bar in bar chart?
I'm using Qt 5.11.3.
I intend to draw a bar chart like this:
The chart will display bars which have the bottom part with another color (e.g. black in this snapshot).
Also, for each bar, I can change the height of the bottom part for any event e.g. every interval....
Can anyone help to give hints or the approach for this. I'm just newbie with Qt.
